This paper describes the interference of surface waves on magnetic fluid and magnetic field produced by a permanent magnet. The dynamic behaviors of magnetic fluid surface subjected to the longitudinal vibration are investigated with a digital high speed video camera system. Two kinds of experiments are performed, that is, on the dynamic response of magnetic fluid in the cylindrical container with a permanent magnet and on the exposed system of magnet-magnetic fluid. Experiments are performed by using a vibration testing system. It is found that the elongated magnetic fluid jet is formed by the stabilization effect of the magnetic fluid at the certain condition of the excitation. The three-dimensional wave motions on magnetic fluid are observed at the exposed system of magnet-magnetic fluid subjected to the longitudinal vibration.
